The baseline_engine and prediction_engine probe queues occasionally turn yellow as seen in the hub Status Tab view in the hub probe.

Cause:

In UIM 8.0, baseline_engine and prediction_engine queues occasionally turn yellow. The queue’s monitored in the hub Status tab window occasionally turn from green to yellow and back to green again. For baseline_engine and prediction_engine, when watching the for queues from the hub status, one might see that the icon/indicator sometimes changes from green to yellow and then back to green again. In the current design, and at an given time/interval, the baseline_engine and prediction_engine periodically resets its own connection to a given queue in order to ensure that the connection stays alive, long term.

Environment:

UIM 8.0

Resolution:

None needed. This is normal behavior, by design, and there are no adverse effects to performance, functionality, and data integrity.
